ISO VG (Viscosity Grade) standards are globally recognized benchmarks for the classification of lubricants based on their kinematic viscosity. These standards ensure that oils meet specific quality criteria and are compatible with a wide range of machinery and applications. Below, we break down the importance, benefits, and applications of ISO VG standards in a detailed table format.
Overview of ISO VG Standards
Aspect
Details
Definition
ISO VG standards classify lubricants based on their kinematic viscosity at 40°C.
Purpose
To ensure consistent oil performance across industries and applications.
Viscosity Grades
Common grades include ISO VG 32, 46, 68, 100, and more.
Measured Units
Viscosity is measured in centistokes (cSt) at 40°C.
Key Metric
A lower ISO VG number represents lower viscosity, while higher numbers indicate thicker oils.
Key Benefits of ISO VG Standards
